Title: Improvements in or relating to mercury vapour power plants
IPC: F22B3/02
Filed: 1940-06-26
Abstract: 538,330. Mercury vapour generators ; stuffing- box substitutes. BRITISH THOMSON-HOUSTON CO., Ltd. June 26, 1940, No. 10900. Convention date, June 28, 1939. [Classes 122 (iii) and 122 (v)] Mercury vapour from a turbine &c. is condensed in a main condensing chamber 11, and leakage air &c. with any entrained mercury is led thence into an auxiliary condensing chamber 16 through which a cooling coil 18 is led to supply the main condenser. A vacuum is maintained in the auxiliary condenser by a conduit 17 leading to a pump. Mercury condensed in the auxiliary condenser is partly returned by an overflow pipe 19 to the main chamber 11, carrying with it any dirt on the mercury surface, while clean mercury is drawn off by a pipe 20 from a vented space covered by a baffle 22. This mercury flows through a cooled chamber 31 open to atmosphere to a centrifugal seal 26 of the turbine shaft, any excess being led back to chamber 31 through a pipe 34. The liquid level in the chamber 31 controls the mercury return valve 40 through a diaphragm 42 subjected on its faces to the pressures in the air and liquid spaces of chamber 31. Any mercury leaking past a labyrinth seal 36 is diverted to a chamber 37 and pipe 38 to the main condenser &c.

Title: Improvements in variable speed belt transmission mechanism
IPC: F16H55/56
Filed: 1949-04-25
Abstract: 666,646. Variable-speed belt gearing. FENNER & CO., Ltd., J. H., MITCHELL, J., and HAINSWORTH, S. B. April 24, 1950 [April 25, 1949], No. 10954/49. Class 80 (ii). A pulley for use in variable-speed belt transmissions comprises conical flanges a, b engaged by a V-belt s, slidably mounted on a sleeve c upon a shaft d, which latter may be, for example, the spindle of a motor. Sliding keys e connect the flanges a, b and keys f connect the flange a to the sleeve c, which' in turn is fixed to the spindle d. Alternatively the flanges a and b can slide directly upon the shaft d. The flanges a and b are drawn towards one another by springs g and h, which are separated by an equaliser k. The equaliser k is engaged at one end i by the spring g which at the other end bears against a nut l adjustable on the hub portion of flange a. A ring m forms a shoulder against which the spring h abuts and which receives screws n securing an end plate o<SP>1</SP>, the other end of the spring h pressing against the flange b. A tubular stem r<SP>1</SP> is screwed into the end of the sleeve c, carrying a collar r<SP>2</SP> against which the cover plate o' is located by nuts v, and having a nipple u through which oil can be passed to the working faces of the hubs of the flanges a and b. When the cover plate o' is fixed, it anchors the equaliser with reference to the sleeve c so as to ensure that the cones move equally towards or away from a median plane between them as the pulley expands and contracts; it also ensures that the springs g, hare equally loaded as the flanges a, b are pressed apart. The pulley is adjusted without the cover plate o' in position, the springs g, h being preloaded by screwing up the nut e, thereby applying pressure to the spring g through equaliser k and spring h to the flange b. The springs g and h, which are equally rated for expansion and contraction under load, are acting in series and therefore must be equally loaded; the cover plate o' is then screwed into position until it just contacts the end. of the equaliser k, and the screws n inserted to .attach to it the ring m. The parts are thereby locked in their position of adjustment. In a modification, not shown, a similar pulley has the end plate o' attached to the sleeve c without provision being made for lubrication. In a further modification Fig. 4, (not shown) the end cover plate o' is omitted, the equal simultaneous movements of cones a and b being ensured by a rocker acting as a link between them. The hub portion of the cone a has a slot in it through which the rocker projects, the rocker being pivoted and having curved ends provided with elastic treads of rubber or the like. Other forms of linkage may be employed, such as a soft-tyred disc, or a gear-wheel, or toothed segments engaging with gear teeth in the hubs. In another modification, the invention is applied, to a double pulley. The invention can similarly be applied to three or more pulleys lying on the same axis.
